SHEET-METAL ROOFING.

Application filed April-10, 1924. Serial No. 705,577.

T 0 0U 'zn/10m t 'may confirm.:

Be 1t known that l, lVrLLIAM STRONG, a citlzen otl the United States,resulmg near Springfield. in the county of Clark and` such a manner ast0 positively prevent the leakage of water at the jointure of the sheetmetal sections.

A further object of the invention is to provide a device of the abovementioned character, wherein the sheet metal sections may beexpeditiously assembled and secured to the sheathing in such a manner asnot to expose the nails or other securing means provided therefor.

A further object of the invention is to provide a device of the abovementioned character, which is simple in construction, inexpensive,strong and durable and furthermore adapted for the purposes fory whichit is designated. i

Other objects and advantages of this invention will become apparentduring the course of the following description.

In the accompanying drawing forming part of this specification and inwhich like numerals designate like parts throughout the saine:

Figure 1 is a sectional view through my invention showing the same inassembled position.

FigureI 2 is a similar view with the parts shown in position previous tothe crimping of the hook portion.

.Figure 3 is a fragmentary detail perspective view of one of the sheetmetal sections.

Figure 4 is a detail perspective view of the securing plate, and

Figure 5 is a fragmentary detail perspective view of the contiguous`sheet metal section.

In the drawing wherein for the purpose of illustration is shown thepreferred embodiment of my invention, the numeral 1 designates asecuring plate which is stamped of metal and is provided with suitableapertures such as are illustrated at 2 for providing a means forreceivingr nails or other suitable fasteningr means indicated at 3whereby the plate is supported on the sheathing A in the manner clearlyillustrated in Figures 1 and 2 of the drawing. Extending upwardly and atan angle to the securing plate 1 along one of the longitudinal edgesthereof is the flange 4. The upper longitudinal edge of the flange 4 iscurved downwardly to provide al hook 5, the purpose of which will bepresently described. j

Supported on the sheathing A, on one side of the securing plate 1 is thesheet metal section G and the same has its longitudinal edge providedwith the upwardly extending flange 7, the same being disposed atsubstantially the same angle as the flange 4 formed on the securingplate 1 and as is clearly illustrated in Figures 1 and 2 of thedrawing,the flange 7 of the sheetmetal section 6 Aabuts the under side of theflange 4.v The upper edge of the flange 7 is provided with a hookportion 8,and the same is of such a construction as to be receivedwithin the hook portion 5 formed on the upper edge of the flange 4.

The contiguous or adjacent sheet metal section 9 is adapted to overlapthe securing plate 1 in the manner clearly illustrated in Figures 1 and2 of the drawing and the longitudinal edge thereof is provided with' theupstanding flange 10 which extends along the upper side face of theflange 4 in the manner as is clearly illustrated in the drawing. Theupper edge of the flange 10 is provided with a depending hook portion 11and the latter is of a greater length and size than the aforementionedhook portion, and the hook portion 11 extends around the hook portions 8and 5.

When the sheet metal sections 6 and 9 respectively are in positlonwithrespect to the securing plate 1 in the manner shown in Figure 2 of thedrawing, the suspending portion of the hook 11 is crimped inwardly asshown at 12 whereby to provide a locking means to prevent the verticalmovement of the section with respect to the adj acentv sec tion andsecuring plate. Inthis manner an interlocking joint for the contiguousseotions of the sheet meta-l roof is provided and the same is of suchconstruction as to pre- 'vent any possibility of water leakingtherethrong The provislon of an mterlocklng joint for contiguous sheetmetal sections of roofing of the class above described is very simpleand effective and will at all times retain the sheet metal sectionssnugly in engagement and there will be no possibility of the scctionsbecoming separated and further by covering 'the securing plate, thefastening means associated therewith will not be disengaged from thesheathing.

While I have shown the preferred embodiment of my invention, it is to beunderstood that various changes in the size, shape and arrangement ofparts may be resorted to without departing from the spirit of theinvention and the scope of the appended claim.

Having thus described my invention, what l claim is In an interlockingjoint, contiguous sheet metal sections of rooting, a securing platehaving one end thereof bent upwardly at an oblique angle to provide ailange, the upper end thereof being curved and terminating in a lip, anobliquely disposed flange formed on the edge of one of said sheet metalsections and adapted to be disposed against one side of theaforementioned liange, the upper edge of the last mentioned iange beingcurved and adapted to be received in the curved portion on the flange ofthe securing plate, the other section being adapted to overlie thesecuring plate, a ilange formed thereon and adapted to extend along theopposite Side of the flange of the securing plate, the upper portion ofthe flange on the second section being curved and disposed over thecurved portion ot' the aforementioned flanges, the curved portion of thelast mentioned flange terminating in a depending strip which is adaptedto be crimped into engagement with the lip formed on the free edge ofthe curved portion of the flange formed on the securing plate, saiddepending portion adapted to be disposed substantially parallel to andspaced from the aforementioned flanges and having an offset eX- tensionat its terminal.

In testimony' whereof I aiiix my signature.

VILLIAM STRONG.
